Which of the following statements regarding carbohydrates is true?

1. They are the body's second source of food

2. They provide no energy

3. They are the body's first source of food

4. They are only necessary in small amounts

The correct answer is: They are the body's first source of food

Carbohydrates are indeed the body's primary source of energy. When consumed, they are broken down into glucose, which is used by the body as fuel for various functions, including brain activity and physical exertion. This energy is essential for maintaining proper bodily functions and supporting daily activities. The classification of carbohydrates as the first source of food highlights their importance in a balanced diet, as they are often the most readily available form of energy in many foods. The context of the other options helps to clarify this point further. Carbohydrates are not the second source of food; they are the first. While they provide significant energy, the statement that they provide no energy is incorrect, as carbohydrates are a primary energy source. Additionally, saying they are only necessary in small amounts does not reflect their role, as they should comprise a substantial portion of a balanced diet to meet energy needs.
